A chain link fence remains one of the most popular fencing solutions for homes and businesses, thanks to its unique blend of durability, security, and affordability. Whether you want to keep pets contained, mark your property line, or add an extra layer of protection to your premises, knowing how to install chain link fence in concrete can ensure your investment stands the test of time.
Setting the posts in concrete, rather than directly in soil, creates a long-lasting, sturdy barrier that holds up to weather and everyday wear. This guide breaks down the entire process into actionable steps, allowing even first-timers to tackle the project with confidence from planning to the final tightening of the mesh.
Planning and Preparation
Installing a chain link fence begins long before you pick up a tool. Proper planning lays the foundation for a straight, sturdy, and compliant fence that meets your needs and local requirements.
Designing Your Fence Layout
Start by measuring the area where you’ll install the fence. Use a measuring tape to record the length of each side, and mark the corners and end points with stakes or brightly colored spray paint. At this stage, also identify where you want to place any gates. Marking these positions ahead of time will help you align your posts perfectly and ensure the finished fence matches your vision.
Always check property lines by referring to your deed or property survey, if available. Accidentally placing your fence a few inches outside your property can cause disputes with neighbors and may even prompt you to move the fence later, leading to wasted effort and expense. Also, review local setback requirements—municipalities often require fences to be placed a certain distance back from sidewalks, roads, or neighboring boundaries.
Checking Local Codes and Utilities
Before you grab a shovel, it’s not only wise but legally required in many areas to call 811. This service will dispatch workers to mark utility lines like gas, water, phone, and electricity, helping you avoid dangerous and costly accidents during excavation.
In addition, check local building codes, permit requirements, and any homeowner association rules that might apply. Many neighborhoods have restrictions on fence height, picket style, or setback from sidewalks, and adhering to these guidelines from the outset can save you from fines or the hassle of redoing your work.
Gathering Your Tools and Materials
Once planning is complete, assemble all the tools and materials needed for a streamlined workflow. A post-hole digger or auger will be necessary for creating post holes, and you may need both powered and manual digging tools depending on soil conditions. A long tape measure, level, string line, and marking tools will help with accurate layout and alignment. Prepare a wheelbarrow and shovel for mixing and moving concrete.
When it comes to materials, be sure to order or purchase enough terminal posts (for corners, ends, and gate posts), line posts (for straight stretches), top rails, chain link fabric (mesh), tension bands, brace bands, post caps, and a sufficient quantity of concrete mix. If you’re installing a gate, don’t forget hinges and latches.
Setting the Terminal Posts
Terminal posts are the structural anchors of your fence—they’ll bear the brunt of tension from the stretched mesh and gate stress, so precise placement and installation matter greatly.
Why Terminal Posts Are Critical
Corner posts, end posts, and gate posts carry all the lateral tension of the chain link fabric and experience the most strain over the life of the fence. If these aren’t perfectly vertical, set deep enough, or anchored securely, the entire fence’s stability may be compromised. Spend extra time on these posts to ensure the entire structure is sound.
Digging the Post Holes
Terminal post holes must be both deep and wide. Typically, dig to a depth that’s one-third the height of the above-ground post, plus an additional six inches for a gravel base—so for a six-foot fence, a 30-inch-deep hole is common. The diameter should be around three times the width of the post; for a 2½-inch post, a hole about 8 inches wide is appropriate. Deeper and wider holes give the concrete a solid mass to resist tipping or frost heaving.
Placing and Bracing the Posts
At the bottom of the hole, add about six inches of drainage gravel. This helps prevent water accumulation around the base, slowing corrosion. Stand the terminal post in the center of the hole, then use a level to ensure it’s perfectly plumb in all directions. If you’re working alone, temporary braces made from wood or scrap material can keep the post in position while you mix and pour concrete.
How to Install Chain Link Fence in Concrete: Process to Follow
Concrete provides unmatched post stability and prolongs the lifespan of your fence. Getting this step right ensures the entire structure stands strong year after year.
Mixing the Concrete
Most homeowners use bagged concrete mix, which is easy to find at hardware stores. Pour the dry mix into a wheelbarrow and gradually add water, mixing with a shovel until the concrete is the consistency of soft oatmeal—moist and workable but not runny. The number of bags needed per post varies based on hole size and depth, but a typical six-foot post in a hole 8 inches wide and 30 inches deep may require roughly two 60-pound bags.
Pouring the Concrete
Carefully pour the mixed concrete into the hole around the post, filling to a few inches below ground level. Use a stick or shovel handle to tamp the concrete down gently, removing air pockets and ensuring a solid fill. As you finish, slant the top of the concrete slightly away from the post (known as “crowning”) to help water drain away and reduce the risk of rot or corrosion at the base.
Curing the Concrete
Let the new posts cure undisturbed for at least 48 to 72 hours. During this time, keep pets and children away, and don’t hang or stretch the fence mesh yet—allowing the concrete to achieve full strength is essential to prevent posts from shifting or leaning later.
Setting the Line Posts
Line posts provide intermediate support between terminal posts, keeping the top rail and mesh straight and preventing sagging.
Marking Line Post Locations
After the terminal posts are set and the concrete has cured, run a taut string line between them at the height your fence mesh will sit. Mark the locations for line posts along this string, keeping them evenly spaced (usually every 8-10 feet). Double-check the position for any obstacles or changes in grade.
Digging and Setting Line Posts
Line post holes don’t need to be as wide or deep as terminal post holes since these posts primarily support the top rail and mesh, not the lateral tension. Dig holes about 6 inches in diameter and 24 inches deep for most residential fences. Place each line post in its hole, use your level to check for plumb, and fill with concrete—following the same mixing, pouring, and crowning procedure as with the terminal posts. Recheck alignment with your string line as you go.
Installing Fittings and Top Rail
The fittings—like tension and brace bands, and post caps—along with the top rail, add further structural integrity and a neat, finished look to your chain link fence.
Attaching Tension and Brace Bands
Before securing the post caps, slide the necessary number of tension and brace bands onto each terminal post. Tension bands will hold the mesh firmly to the posts, and brace bands are used for attaching the top rail. These bands should be installed in the right sequence—usually starting at the bottom and working upward—as specified by your fence plan or manufacturer’s instructions.
Installing Post Caps
Post caps serve a dual function: they prevent water from entering the post and provide a smooth, finished look. Place domed caps atop each line post. For terminal and gate posts, use specialized post caps designed to accommodate the top rail.
Assembling the Top Rail
Fit the top rail through the post caps atop each line post, connecting sections by inserting the smaller, swaged end into the plain end of the next rail. The rail should run continuously from one terminal post to the other, providing a stable framework along which the chain link fabric will be attached. Fasten it securely using rail-end brackets and brace bands at the terminal posts.
Stretching the Chain Link Fabric
This step brings the fence to life—unrolling the wire mesh, stretching it tightly, and securing it for years of durability.
Hanging the Mesh
Position the chain link fabric roll next to a terminal post and stand it upright. Insert a tension bar vertically through the end links of the mesh. Attach this bar to the tension bands on the terminal post using carriage bolts and nuts—this ensures the mesh is anchored evenly and tightly along the post.
Using a Fence Stretcher
To achieve a taut, professional finish, use a fence stretcher or come-along tool. Hook the tool onto the opposite end of the mesh and pull until the fabric becomes firm and gives only slightly when pushed. Stretching the mesh too tightly may buckle the material or lift posts, while leaving it too slack results in sagging. Check the manufacturer’s guidance for the proper amount of tension.
Securing the Mesh
With the mesh tensioned, insert a second tension bar into the end links at the other terminal post and attach it to the post with its tension bands. Before trimming excess mesh, double-check your work to ensure the fabric is uniformly tight and there are no gaps at the ground or along the posts.
Tying the Fence to the Rails
Once the mesh is secure at both ends, fasten it to the top rail and line posts for a finished, stable wall.
Attaching the Mesh to the Top Rail
Fence ties—short pieces of pre-cut wire—are used to bind the top of the chain link fabric to the top rail. Space these ties about every 24 inches, wrapping them tightly so the mesh won’t lift or sag. Twist the ends neatly on the side facing away from traffic to reduce snagging.
Securing the Mesh to the Line Posts
Attach the mesh to each line post using fence ties at three or four equally spaced points. This further stabilizes the fabric along the length of the fence and helps prevent movement or bulging.
Installing a Tension Wire (Optional but Recommended)
While not always required, adding a tension wire at the base of the fence adds another layer of animal and security proofing.
Why Use a Tension Wire?
A bottom tension wire prevents the mesh from being pushed up by animals or people and helps maintain a clean, taut line along the base of your fence. Without it, dogs and wildlife may burrow under the fence or lift the mesh, creating gaps.
How to Install It
Before attaching the mesh to the line posts, string the tension wire along the bottom—thread it through the lowest row of chain links or clip it to the mesh using special fasteners. Secure it firmly at each terminal post and stretch it tight to ensure maximum effectiveness.
Common Mistakes and Troubleshooting
All construction projects can encounter obstacles. Recognizing and avoiding common issues can save headaches down the road.
Posts Leaning After Curing
If a post ends up leaning after the concrete sets, it’s often traced to improper bracing during curing or using an overly wet concrete mix. Always ensure posts are solidly braced and your mix is properly proportioned.
Sagging Fence Mesh
A loose or sagging fence is typically caused by insufficient tension during stretching. Don’t rush this step: use proper tools and techniques, and don’t be afraid to start over if the fabric isn’t tight enough on the first try.
Incorrect Post Depth
Shallow post holes are a leading cause of long-term fence problems, particularly in areas with frost. Posts that aren’t set deep enough are prone to heaving, tilting, or even uprooting during seasonal changes. Double-check recommended depths and always err on the side of a deeper, sturdier foundation.
